Figs. 6, and 7 ,are diagrams of the valve action.

Figs. 8, and 9, are diagrammatical views of the crank shaft and floats connected thereto.

Fig. 10 is a diagrammatical viewof the dam and housings. I v In Fig. 1, 1 represents a concrete dam, 2 represents the water on the up streamside of said dam, 3 is a concrete wall supporting one side of the motor housings, 4 is the reservoir between said dam and motor housing, said reservoir being supplied with Water through a conduit 5, which passes through the concrete dam, and on one end of said conduit, is a gate valve 6, having a stem 7, vertically positioned and slidably mounted in housing 7, supported by bracket 8, and on the upper end of said stem is a hand wheel 9, functioning as means for opening and closing said valve.

In Fig. 1, is shown a form for constructing the housings of the float, valves, and crank shaft, the said housing being con structed of metal having side Walls 10, and partitions 11. is rigidly attached to the concrete walls 8, the said housing having a cover 12. On the opposite side from said spout is an inlet opening 14-, in which is a rotatably mounted valve 15. In said spout 13 is a rotatably mounted valve 15. The said valves seating in their respective openings as at B, and are water tight when engaged for the purpose hereinafter described. 16 is a valve operating bar being pivotally connected to said valves as at O, and intermediately disposed in said bar is a yoke 17, engaging on a cam 18, which is rigidly mounted on a crank shaft 19, the object of which is, by the rotation of said shaft the said bar will reciprocate, and being pivotally attached to the valves, will cause them to rotate, opening and closing alternately receiving and discharging the water, actuating the floats.

On said shaft is a crank 20, adapted to engage the end of a connecting arm 21, and on the opposite end-of said arm is pivotally connected a float 22 to be submerged, and buoyancy thereof, is the actuatingineansfor rotating said shaft.

It will be understood that the crank shaft herein referred to will have a plurality of cranks interposed therein and positioned so as to time the rotating element in conjunction with each other, producing a continu ous rotation of the shaft, and on the end of said shaft is a flywheel 28, said wheel being properly housed, and on either end of saidshaft may be placed a gear, or other power transmitting element for transmitting power to a generator, pump, or other mecha nism to be energized, said shaft being trunnioned in a bearing 24- substantially as shown or equal thereto, and for installing or removing the shaft, I have provided a slot 25, which'is covered with a gasket securely held in position by means of bolts 26, the object One of said Walls as at A,

of which is to prevent the flow of the water from one compartment to the other so the filling and discharge of the water from each compartment will be independent of the others, reciprocating in their action, and having a plurality of compartments, having housed therein a crank, float, and valves for the inflow and discharge of the water, the said cranks being radially disposed and properlytimed, a continuous rotating tension is maintained.

In F i is shown a style of dam bein channeled as at 27, the said channel adapted to receive the buoyancc motors, the said motors being separated by partitions 28, and the valves 15 mounted in ducts 29, said ducts being fed by longitudinally disposed con-- duits 29, and said valves functioning as heretofore described.

In said channel is positioned a ladder 80, and a tram 31, by which means access may be had to the machinery for inspection, the top of said channel being covered as at 32. has a man hole 38 adjacent to said ladder.

In this style of dam I have provided a slidably mounted cut off 34:, which is adapted to close the supply duct 29, and is operated by a connecting rod 35, extending upward and pivotally connected to a lever 36, which is mounted on a lever 37, when said out off is raised or lowered it is held firmly in psition by a pawl engaging in a notched sector 88.

In Fig. 5, is shown a dam 39, impounding the water supply as shown at level 4-0, said water being conducted through conduit equivalent to 5, as shown in Figure 1, and the controlling means being similar thereto. On the down stream side of said dam are located in cascade, a plurality of motors as described heretofore, these motors being so arranged that the water discharge from the conduit into the dispensing reservoir of the first housing is released into the dispensing reservoir of the lower adjacent housing after the cycle of operations of the various compartments have wasted the water through their respective discharge valves, and so on through the succeeding housings to the low point of the down stream of the dam 39, each motor has a flywheel 22-3, on one end of its shaft to insure smooth rotation, and on the opposite end of said shaft a worm gear 41, engaging a spur gear 42, said spur being firmly fixed on rotatably mounted counter shaft 43 supported by a thrust and other bearings, said counter shaft having a plurality of worm geared transmissions transmitting power from a plurality of motors arranged for this purpose in the manner heretofore described.

The counter shaft transmits the delivered power obtained from the plurality of water motors to bevel gearing 44, arranged in pent house 45, as shown from which power may be obtained for the operation of such machinery as may be contemplated. In Fig. 5 the third housing D, as shown has parts removed for the convenience of illustration the yoke and valves being omitted showing the dispensing reservoir of this housing feed through the discharge the spout E, of the upper adjacent housing, and in turn discharging into the dispensing reservoir 1 of lower adjacent housing for its operation. The operation of the plurality of motors in cascade will be so timed that a continuous torque will be exercised on the counter shaft through the plurality of worm gears heretofore described.

Figure 6 shows the cam 18 engaging yoke at the point of discharge through valve the crank being on the upper dead center and the cam continues to hold valve 15 in open position, and opposite Valve 15 in closed position for the duration of time expended by the crank to recede its lower dead center, at which time valve action is reversed as shown in Figure 7 and remains in this position until crank reaches upper dead center whereupon the action described in connection with Figure 6 again ensues. Fig. 6 shows position of valves when discharging water from motor housing, Fig. 7 shows position of Valves when the discharge valve is closed, and the intake is open allowing water to enter motor housing, and engaging the float for the purpose set forth.

Fig. 8 is an end View of the diagrammatic position of the floats in relation to their respective cranks and their position longitudinally is as shown in Fig. 9.

Such modifications may be employed as lies within the scope of the appended claims and what I claim as new and desire to secure by Letters Patent is 1. In a hydraulic motor, a dam, a plurality of housings in axial alignment and paralleling said dam, a crank shaft positioned longitudinally in said housings, said shaft having a crank, a float and cam, supply and exhaust valves,'a bar actuated by said cam, said bar adapted to open and close said valves alternately for receiving and discharging the water, substantially as shown and described.

2. In a hydraulic motor of the kind described, a dam, and a plurality of motor housings horizontally disposed and paralleling said dam said housings being on the downstream side of said dam, and placed in cascade, in engaging relation to each other consecutively, a crank shaft, float, and valves interposed within each of said housings, a flywheel on the ends of said shafts, a worm gear on the opposite end thereof, a counter shaft rotatably mounted in axial alignment with the ends of said shafts, spur gears rigidly mounted on said counter shaft and adapted to engage with said worm gears, the

lift) said shaft functioning as power transmitting means substantially as shown.
